H, J. SCHNEIDER DYNAMIC -DEAERATOR AND WATER HEATER 2 Sheets-Sheet 2 Filed Feb. 26, 194 0 Patented Mar. 18, 1941 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a combined deaerator and water heater and it consists in the constructio-ns, arrangements and combinations herein described and claimed.

It is the object of my inventionto provide a deaerator heater in which the water passes through a substantial number of tubes, the-latter being heated by steam, and in which water from the tubes is discharged, spread and agitated by means of steam actuated turbines, the dynamic action permitting liberation of air, oxygen or impurities which are a detriment to steam generation, as Well as appliances.

Specifically, it is an object of the invention to provide a deaerator embodying a plurality of rotatable units for discharging water over a considerable area, and in which each unit includes a turbine positioned upon opposite sides of a common steam pipe, the pipe having nozzles for discharge of steam against the turbine to impart rotation thereof.

It is also an object of the invention to provide a deaerator consisting of a plurality of units mounted upon a base which may be readily removed from the deaerator casing for repair of the parts.

Additional objects, advantages and features of invention will be apparent from the following description, considered in conjunction with the accompanying drawings, in which Figure 1 is a cross section of my dynamic deaerator and Water heater.

Figure 2 is a longitudinal sectional view.

Figure 3 is a plan view of unit A of Figure 1.

Figure 4 is a cross section on the line A-A of Figure 1.

In carrying out my invention, I provide a casing 30, in the present instance being shown as of cylindrical form, having a water inlet 2| and outlets 22. A bank of water pipes i8 are connected between the inlet 2| and outlet 22, and as shown, the pipes are positioned in the uppermost portion of the casing. An exhaust port I is provided in the casing, above the pipes 18, allowing steam to pass therethrough to a steam condenser, not shown. The outlet 22 includes a pair of water pipes 3 and I9 extended longitudinally of the casing immediately below the lowermost pipes l8 and spaced a like distance from the axial center of the casing as best seen in Figure 1.

A steam pipe [5 is arranged through the longitudinal center of the casing, having an inlet 25 and an exhaust outlet 26. A platform [3 is removably supported within the casing 30, in the present instance, longitudinally extended lugs 3| slidably. receiving the platform. The casing includes removable end walls 32, permitting insertion and removal of the platform. The .platform 13 is perforated, as shown in Figure 2, permitting free passage of water to the lower portion of the casing, and a perforated .plate 20 is positioned below the platform l3, the latter plate serving as a strainer, to prevent foreign matter passing into the lower portion of the casing. This plate is also removable for cleaning purposes. The lower portion of the casing has a pipe 2'! for connection with a suction means of a boiler feed pump not shown, and also has a drain connection 28.

Upon the platform [3 there are mounted a pluraility of upright rotatable shafts l0 supported in bearings l l and 12, the shafts l0 being spaced longitudinally along the platform in pairs upon opposite sides of the steam pipe l5. Each shaft It) has fixed'thereon a turbine wheel IS, the vanes of which are presented to respective steam nozzles I4 of the pipe IS.

The deaerator units are of identical construction and a description of one will be suflicient for an understanding of the device. Above the turbine wheel I6 there is rigidly secured to the shaft I0 an annular disk 9, the latter having a perforated periphery and an inwardly turned upper edge.

Concentric with the shaft Hi, there is an annular spray pipe 2 having communication with water pipes 3 or l9, as the case may be. Radially disposed gusset plates 5, 6, I and 8 are fixed to the pipe 3 or l9, extended downwardly and have secured at their ends a perforated annular disk 4. The disk 4 remains stationary and is additionally supported by reason of engagement of the shaft I0 \m'thin the bearing H.

,"I'he disk 9 has a multiplicity of apertures formed in the periphery of the upturned edge in order that water may be discharged centrifugally, under rotation of the disk, and in order that the water discharged may thoroughly be broken up, there is provided a cylindrical deflector plate IT. The plate I| may be supported from the platform in any approved manner.

In use, water passes through the pipes 3 and I9, through the spray pipes 2 downwardly on to the disk 4, through the apertures of the disk and into the rotatable disk 9. Steam enters through pipe I5, being discharged through respective nozzles l4 so that the steam impinges against the vanes of the turbine l6, causing rotation of the disk 9, with consequent discharge of water through the apertures of the disk into forcible contact with the deflector plate I1. Thus the water will be thoroughly agitated and broken up in a fine mist so that impurities are released. While I have shown and specifically described my invention, this is by way of illustration only, and I consider as my own all such modifications as fairly fall within the scope of the appended claims.

I claim:

1. In a dynamic deaerator and water heater, I

a casing having a multiplicity of water pipes in an upper portion thereof, inlet and outlet means for the pipes, said casing having a steam exhaust port above the pipes, a pair of water pipes connected with the outlet means ofthe water having nozzles for discharge of steam against the turbine wheel.

2. In an dynamic deaerator and water heater, a casing having a multiplicity of water pipes in an upper portion thereof, inlet and outlet means for the pipes, said casing having a steam exhaust port above the pipes, a pair of water pipes connected with the outlet means of the water pipes, said pair of water pipes being extended into the casing in parallel spaced relation, a plurality of annular spray pipes spaced longitudinally of and connected with said respective pair of pipes, a perforated disk suspended from each of said spray pipes, a perforated platform within the casing, vertically disposed rotatable shafts on the platform, one shaft being axially positioned beneath each of said disks, a disk fixed to each shaft, said disk having an annular perforated wall, a turbinewheel on each shaft, a steam pipe within the casing and positioned longitudinally between the upright shafts, said steam pipe having a nozzle in operative relation to respective turbine wheels, and an annular deflector plate circumscribing said disks.

3. The structure of claim 2 in which the easing is provided with detachable end walls and said platform is removable from the casing.
